Claims. (Cl. 112-2) My invention relates to a new and improved apparatus and method'for hemming the ends of a necktie.

It has been well known practice for many years to provide the blunt or the tapered ends of a necktie with hems in order to eliminate the raw edges of the material. The hems are formed after the flat necktie blank is cut and prior to folding the blankor other operations.

In making the better grade of necktie, the hems have been formed by hand. Such hand work has been expensive.

The object of this invention is to provide a simple and cheap apparatus and method whereby hems are formed which simulate the appearance of the hand-made herns, and which can be made at much lower expense.

According to my invention, the end of the fiat and unfolded necktie blank is pulled through a hemming device by a feed which is provided by a feeding and hemming strip which is moved in unison with the blank through the hemmer. This feeding and hemming strip is made of material which is easily folded and creased. This feeding and hemming strip may be made of paper. The hem is formed simultaneously in the material of the necktie blank and the strip. The necktie blank is fed towards the hemmer and through the machine by an endless conveyor belt.

The feeding and hemming strip is pulled in the feeding direction by a feed wheel and by pull rolls. One-pair of pull rolls moistens the combination hem and presses it. The other pair of pull rolls dry the combination hem.

The feeding and hemming strip is then removed from the combination hem. The resultant hem in the material of the blank has sharp folds or creases after the feeding and hemming strip has been removed, and said hem can be easily and accurately sewed by hand.

In making the combination hem, the feeding strip may be applied to either face of the necktie blank.

The invention is further explained in the annexed description and drawings, which illustrate one embodiment of the improved machine.

Figure l is a side elevation of the improved machine, with certain of its parts shown broken away in order to illustrate other parts.

Fig. 2 is a top plan view of the machine.

Fig. 3 is an end elevation taken at the right end of Fig. 2.

Fig. 4 is a transverse section, which shows the feeding and hemming strip applied to the inner side of the fabric of the necktie blank. As above noted, said strip may be applied to either side of the face fabric of the necktie blank.

Fig. 5 shows the completed combination hem, if the necktie blank does not have a fabric facing strip or a lining strip which is part of the final necktie.

Fig. 6 is a sectional view which shows the completed combination hem, if the necktie blank has a fabric facing layer at its inner side as part of the completed necktie.

Fig. 7 is a perspective view of a guide which may be used, in the machine.

2,748,729 Patented June 5, 1956 Fig. 1 shows a frame F which is supported on legs 1. A table T is fixed to the frame F by means of vertical legs 2.

A feed wheel 3 is fixed to a shaft 4, which is mounted in bearings 5 of frame F.

As viewed in Fig. 1, the feed wheel 3 is turned clockwise. This feed wheel 3 is optionally provided with ratchet teeth 6, in order to engage the fabric of the necktie blank N or to engage the feeding and hemming strip P in order to feed the blank and the feeding and hemming strip more efficiently.

A presser foot 7 is fixed to a vertical rod 8, which is slidable in a vertical bearing 9 which is fixed to a vertical rod 14) which is fixed to the table T. The rod 8 of the presser foot 7 also extends vertically through a vertically adjustable bearing 11, which is provided with a bore through which the rod 10 extends. This rod 10 is of rectangular cross section and the bore of the supplemental bearing 11 is also of interfitting and rectangular cross section, so that the supplemental bearing 11 cannot turn on the rod 10. The rod '8 fits similarly in its bearings, so that rod 8 cannot turn.

A compression spring 12 is mounted upon the rod 8. This compression spring 12 abuts bearing 11 and the top of presser foot 7, and exerts pressure upon the presser foot 7 so as to urge it downwardly. An adjusting screw 14 is threaded in a lug 15 of the rod 10. The bottom end of screw 14 abuts the top of bearing 11. By turning the adjusting screw 14, the bearing 11 can be slidably adjusted on the rod 10, thus regulating the pressure of the spring 12.

The presser foot 7 has an arched shape, which corresponds to the shape of the periphery of the feed wheel 3. The feed wheel 3 is located in a lateral opening of the table T, so that the layers of material which are to be hemmed, can be fed along the top of the table T, between the presser foot 7 and the feed wheel 3.

Fig. 2 shows a necktie blank N. This is a flat fabric blank of unfolded material. This blank N is shown as having tapered ends, which have edges 33a and 33b, which are perpendicular to each other and meet at point 33d. This blank N is originally fed through the machine in the first hemming stroke, in the full-line position shown at A in Fig. 2, or in the broken-line position shown at C, in order to hem either the edge 33a or the edge 33b in the first stroke. The blank N is then fed through the machine in either said A or C position to hem either edge 33a or edge 33b, and it is then fed in the other position to hem the other edge.

The necktie blank N is fed through the machine by means of an endless feed belt which has a top run 16 and a bottom run 17. This belt 16-47 is mounted upon pulleys or rollers 18 and 19. The pulley 13 is provided with a shaft 20 which is mounted in bearings 21 which are fixed to the frame F. As shown in Fig. 2, this shaft 20 of pulley 13 extends horizontally and laterally beyond the rear of frame F and the belt 16-17. Laterally behind the frame F and the belt 16-17, the shaft 20 is provided with a sprocket 22, which is connected by a chain 23, shown in Fig. 1 and Fig. 3, to driving mechanism which includes a drive sprocket 24, which is shown in Fig. 3. Fig. l and Fig. 3 show an electric motor M, which actuates conventional speed-reduction gearing R, whose well-known details are not illustrated. As shown in Fig. 3, this reduction gearing R has an outlet shaft 25, which is driven by said reduction gearing at lower angular velocity than the shaft of motor M. This shaft 25 can be coupled to an alined shaft 26, by conventional coupling mechanism which is automatically uncoupled, after the alined shaft 26 has turned a complete revolution. The alined shaft 26 is connected through a conventional step-up drive Ra to the shaft 27 of the sprocket 24. This shaft 27 is turned at greater angular velocity than shaft 26.

Without limitation thereto, and only as one example, the sprocket 24 is turned two and one-half complete revolutions for each revolution of the shaft 26, thus actuating the conveyor belt 16-17 sufficiently in one revolution of shaft 26 to move the blank N from the inlet station A or inlet station C to the respective final or outlet station B or D. Station A corresponds to outlet station E, and station E corresponds to outlet station D.

The coupling between the shaft 25 and the shaft 26 includes coupling drum-members 28 and 29. Drum 28 is fixed to shaft 25. Drum 29 is fixed to shaft 26. These coupling members 28 and 29 may be of any well-known and conventional type and their details are not illustrated in the drawings for this reason.

According to one well-known coupling system, the right vertical face of drum 28, as viewed in Fig. 3, has a series of equally spaced holes which are radially equidistant from the common axis of shafts 25 and 26. The left face of drum 29 has an axially movable pin which is urged axially by a spring from a normal uncoupling position, to a coupling position in which said pin enters the axially alined hole, in order to couple drums 28 and 29, so that said drums and their shafts 25 and 26 turn in unison. This pin has the usual tapered end and a cam face. When the shafts 25 and 26 are uncoupled, at the beginning of a feeding stroke of the feed belt, the cam face of said pin contacts with the cam face which is provided at the end of a lever 30, which is pivoted at 31a, and which is integral with foot pedal 32. A tension spring 31 yieldingly holds lever 30 in its position of Fig. 1, in which the cam face at the end of lever 30 abuts the cam face of said axially movable pin, thus holding said pin, in uncoupling position, and axially alined with one of said holes. At the beginning of a feeding stroke, the operator presses upon pedal 32, thus moving lever 30 out of engagement with said coupling pin, which enters the alined hole, thus coupling shafts 25 and 26. After said shafts 25 and 26 and their drums 28 and 29 begin to revolve in unison, said coupling pin clears lever 30. The operator then releases pedal 32, so that lever 30 is moved by spring 31 back to the normal or original position of lever 30 which is shown in Fig. 1. When the drums 28 and 29 and their shafts 25 and 26 have turned through a complete revolution, the coupling pin is moved back to its original position in which the cam face of said coupling pin engages the cam face at the side of lever 30, so that lever 30 axially shifts said pin to uncoupling position.

Another conventional governing device for stopping the turning of shafts 25 and 26 at the end of a complete revolution is described at pages 132-133 of The Engineers Sketch Book of Mechanical Movements, Devices and Details, by Barber, th edition, published by Chemical Publishing Co., Inc., whereby a catch is thrown out at the end of a revolution.

As shown in Fig. 2, the table T is provided with a longitudinal guide 33 for guiding the edge 33a or 33b of blank N. This guide 33 has a lateral angular shape, with a vertical leg and a lateral leg, in order to guide the edge 33a or 33b of the blank N in the respective hemming stroke.

The horizontal leg of this guide 33 is fixed to the table T by means of screws 34.

As shown in Fig. 2, a front part of the necktie blank N overlies the front edge 16a of the top run 16 of the belt during the respective feeding stroke.

The operator places the blank N upon the top longitudinal run 16, so that the front part of blank N, which extends laterally in front of the front edge 16a of top 16 is supported slidably upon the table T. If the edge 33/: is to be hemmed, said edge 33a slidably abuts the vertical leg of guide 33, so that the blank N is moved longitudinally from left to right, in unison with run 16a, towards and into the hemmer 35, to which a feeding and hemming strip P of paper or other material is fed from a roll Pa.

The operator keeps his hand upon the blank N, while blank N is thus moved by top run 16. In starting the machine, and before the first feeding stroke, the end of the hemming and feeding strip P is pulled by hand through the hemmer 35 and between the feed wheel 3 and the presser foot 7, and also between the two pairs of rolls later mentioned herein, so that the hemrning and feeding strip P is continuously fed from left to right during each feeding stroke. The feeding and hemming strip I thus overlies the fabric material of the necktie blank N at the inlet of the hemmer 35, and in the hemmer 35, and the combination hem or fold is formed in die blank N at its edge 33a and also in the strip P, in the hemmer or folder 35. The operator holds the blank N in position on run 16 of the belt, while the edge-part of the blank N is being fed to the hemmer 35. The pull of strip P pulls blank N through hemmer 35.

The original width of the flat and initially unfolded paper strip P, as it enters the hemmer 35, is shown in Fig. 2 at the left of the hemmer 35 and also above the hemmer 35. This original flat and unfolded width of strip may be 0.75 inch. The length of the edge 33:! or 33b of the unfolded blank N is usually 8 to l0 inches.

Fig. 5 shows the combination fold or hem H which is formed in the folder hemmer 35, which may be of any conventional type. This hem H is shown in the unpressed state in Fig. 5.

It would be impossible to form an accurate hem in the material of the blank N, without using the strip 1. This strip P is preferably made of soft and easily folded paper, of the kind which is used in pleating fabrics. The strip P gives the proper body to the material of blank N, in order to form an accurate combination fold or hem H.

This hem H is flattened and the folded strip P therein is creased, by the pressure between feed wheel 3 and the presser foot 7. Said foot 7 exerts only light pressure, just enough to feed the layers of material by means of feed wheel 3.

The blank N and the strip P are dry and at ordinary room temperature of 20 C.-25 C., while they pass through hemmer 35 and between feed wheel 3 and presser foot 7.

Beyond the presser foot 7, the combination hem H is passed between a perforated steaming and ironing roll 36 and an auxiliary pressure roll 36a. The combination hem H is steamed and ironed to fiat condition between rolls 36 and 36a. The roll 36 is mounted on a hollow shaft 37 which is provided with bearings in the frame F. This shaft 37 may optionally have one or more perforations within roll 36.

The machine is provided with a steam inlet 38 which is connected to any suitable source of steam, such as a boiler. This inlet pipe 38 is connected by a branch pipe 39 to the hollow shaft 37 of the roll 36. This shaft 37 has an opening, as above noted, through which the steam passes from shaft 37 into the interior of the hollow drum or roll 36, and this drum or roll 36 is provided with perforations, through which the steam can flow so as to moisten the combination hem H in the ironing operation. The companion roll 36a is forced under suitable pressure against the top of the combination hem H so that the top pressure roll 36a is rotated by the frictional drive of the steaming and ironing roll 36.

The steam softens the fibers of the fabric. The creases or folds at the edge of the combination hem H are thus formed sharply and accurately.

The moistened and ironed combination hem H is now passed between a pair of drying rolls 40 and 40a. The roll 40 is not perforated. It has an imperforate or perforate hollow shaft 41 to which the branch pipe 39a of the steam line is connected in order to heat said roll 40. The rolls 40 and 40a may be heated electrically. Roll 40:: is driven by roll 40 through the friction of hem H.

The heat which is supplied by the rolls 40 and 40a dries the hem and also provides additional ironing action.

As shown in Fig. 2, the shafts 4, 37 and 42 of feed wheel 3 and of the lower ro'ls 36 and 40, are provided with sprockets which are connected by an endless chain 45 with a sprocket 45b on shaft 20. p

The top run 4511 of endless chain 45 is shown in Fig. l and Fig. 2. The bottom run of chain 45 is not shown in Fig. 1, because it is concealed by frame F. A part of the representation of top run 45a is omitted in Fig. l.

The feed wheel 3 and the pairs of rolls 3636a and 4040a are turned at the same circumferential or peripheral speed as the linear velocity of the conveyor belt 16-17.

Fig. 7 shows a guide 56 which has a plate 47 which can be fixed to the table T, and a channel-shaped guide portion 48 which has a lip 49 which is located above the plate 47. One or more of these longitudinal guides 46 can be provided on the table T between the outlet of the hemmer and the outlet end of the machine. These guides 46 can be located at the right of the feed wheel 3, or between feed wheel 3 and the rolls 3636a, or between rolls 36-36a and the rolls -4051.

The longitudinal distance between the outlet of the hemmer 35 and the front or left side of the presser foot 7 is less than the length of the edge 33a or 33b. These edges 33a and 33b are of equal length. The longitudinal distance between wheel 3 and rolls 36-36a, and between rolls Ito-Second rolls id-4th is less than the length of the edge 33a or 33b which is to be hemmed.

At the beginning of a stroke, the operator adjusts the blank N in proper position on belt 16-47, using the guide 33 for correct adjustment, and the operator moves his hand along with the conveyor belt 16-17 and blank N, until the blank N enters the hemmer 35. The frictional grip and pull of the strip P will then automatically pull the blank N in unison with the belt 1617. As above noted, the feeding speed of the feed wheel 3 and of the drums or rolls 36-36a and 40--40a is equal to the longitudinal speed of the belt 16-17. Therefore, the feed wheel 3 will pull the blank N and the strip P in unison with and at the same longitudinal speed as the belt l6-i7 and the same applies to the rolls 36-36(1, and the rolls 4tl4tta.

When the blank N has reached the end position at station B or D, the strip P is out. For this purpose,

a stationary shear blade 50 is fixed to the frame F, and

:a turnable shear blade 51 is pivoted at 52 to the frame F. A link 53 connects the turnable shear blade 51 to the core or plunger 54 of a solenoid S. A tension spring 55 normally keeps the pivoted blade 51 in its upper and non-cutting position.

The coil of the solenoid S is provided with current from any suitable source and the normally open circuit of said solenoid S and of said source includes wires 56 and 56a and a switch 57. This switch has an operating button 58. When the operator depresses the pedal 32, this pedal closes the circuit of the solenoid S by depressing button 58, thus closing switch 37 and the circuit of solenoid S, thus downwardly turning the pivoted shear blade St to cut the strip P.

In actual practice, the cut-off part of strip P in hem H is removed from the hem H before the hem of the fabric of blank N is sewed. However, the labor of handsewing is greatly diminished and the accuracy of the sewing is increased because the operator can follow an accurately pre-formed hem which has sharp and accurate folds or creases.

After the hem has been sewed along the edge 33a, if this is the first edge to be hemmed and sewed, the blank N is passed through the machine from position C to the broken line position D, thus forming a corresponding hem at the other edge 33b.

Preferably the blank N is in its initial broken-line position at station C, in its first pass through the machine.

6 In such case, the point 330 will be anterior the tip 33d of of the necktie blank N in said first pass.

This will form a first hem which is folded to the left, as viewed by a person standing at the left end of Fig. 2.

In the second pass, the blank N will be in the full-line position at station A, so that the point 33d precedes the point 33c. This will form the second and overlapping fold or hem at the other edge, also folded towards the left. and provide the desired neat appearance at the point 33d.

Some neckties, even of good quality, have a straight horizontal edge, instead of the tapered end shown in Fig. 2. In such case, it is necessary to use only a single pass or stroke and to form a single hem at said edge.

It is obvious that the blank which is hemmed, need not be the complete blank N of the entire necktie. A necktie blank is ordinarily made of two parts which are sewed together to provide the entire length of the blank. One of these parts can be hemmed as previously described, and the hemmed piece can then be sewed to the other part of the necktie blank.

Fig. 6 shows a necktie blank N which has facing fabric Na sewed to its inner face. This blank N is handled as previously described. Therefore, in this instance, three layers of material are passed through the hemmer and the combination hemH is shown in Fig. 6.

The bottom face of the presser foot 7 can have a longitudinal groove which the combination hem enters vertically either partially or wholly, in order to facilitate the feed of the layers and to provide an accurate location of the hem.

Instead of having the arched shape shown in Fig. 1, the presser foot 7 may have a flat or planar shape.

The guide 46 shown in Fig. 7 can also be greatly moditied in shape instead of having the angular shape shown therein. Thus the channel of the guide 46 can follow the shape of the combination hem shown in Fig. 5 and Fig. 6, which have rounded corners.

In Fig. 5 the bottom face of the blank N, marked as E, is the exposed face of the necktie when it is worn. In the machine shown herein, the hemmer 35 folds from right to left, as viewed at the left side of Fig. 2. The ordinary hemmer folds in the reverse direction, namely, from left to right as viewed at the front of Fig. 2. If an ordinary hemmer is used, the face E of the necktie must be the top face of the material of blank N which is fed through the hemmer 35 and the strip P will abut this face E.

The strip P may be either at the top or at the bottom of the blank of Fig. 5 while the hemming is being done. Similarly, in forming the combination hem H shown in Fig. 6, there may be any relation between the relative positions of the strip P and the layers Na and N, so that the strip P may touch Na or it may touch N and the fabric layers may be above or below the strip P.

Also, the hemmer and the rolls and feed wheel may be adjacent the left edge of the belt, as viewed at the left end of Fig. 2.

At the beginning of each folding or hemming stroke, the supplemental strip P is in flat form anterior the folding or hemming zone which is defined by the folder or hemmer 35. Said strip P may be provided with a guide roll anterior the folding or hemming zone, so that the fiat anterior part of strip P contacts in flat form with the flat edge-portion of blank N, at any desired distance anterior the folding or hemming zone. At this time, the strip P then extends longitudinally from its said flat part, through said hemming zone, also through the pulling zone 37, also through the pulling and ironing zone 36-36a, and also through the pulling and drying zone 40-40a, up to the cutting zone 5051.

Said strip P is in laterally folded shape at that time, in the hemmer 35.

The flat and free-edge portion of the necktie blank N, which extends laterally in front of the edge 16a, is-ap- 7 plied to said flat anterior part of strip P, anterior the hemming or folding zone.

One edge of strip P is substantially coincident with the edge 33a or 33b of blank N at which the combination fold or hem H is to be formed.

A longitudinal pull is then exerted upon the strip P in a pull-zone or pull-zones which succeed the folding or hemming zone.

The edge-portion of the fiat blank N is moved longitudinally in unison with the longitudinal movement of strip P, through the folding or hemming zone, While the fiat part of strip P and the edge-portion of the blank N are laterally folded or hemmed under tension in the folding or hemming zone, to produce the combination fold or hem H. This tension is maintained in the succeeding steaming and ironing zone 3636a, and in the succeeding drying and pressing ZOne 4040a, because the rolls 3636a engage the right end of the fold or hem H before it is released by feed-wheel 3 and presser-foot 7,

and the rolls 4040a engage the right end of the fold or hem H before it is released by rolls 36-36a.

The rolls 40-40a push the finished combination fold or hem H and the strip P to the final position shown in Figs. 1 and 2, and the strip P is cut at the left of the finished fold or hem H, thus leaving the uncut part of strip P in operating position anterior the cutting zone which is provided by the cutters 5051.

These operations can be performed by hand and by many different types of machines, so that the method claimed herein is not merely the function of one machine.

In general, I claim a method whereby a flat edge-portion of a necktie blank is applied to a flat part of a supplemental strip anterior a folding or hemming zone and anterior one or more pulling zones which succeed said hemming zone, said fiat supplemental strip extending initially through said folding or hemming zone and through said succeeding pulling zone or pulling zones at the time that said necktie blank is thus applied. Said fiat part of said supplemental strip and said fiat edge-portion of the necktie blank are then fed rearwardly in unison through said folding or hemming zone, then through a pressure zone and then through a cutting zone in which the supplemental strip is cut forwardly of the finished hem or fold.

Whenever I refer to a hem, I include a simple fold, in which the folded material is folded along a single foldline, although I prefer to use a plurality of fold lines.

The use of the pulling means 3 and 7, anterior the pulling and steaming and ironing zone 3636a, is highly preferred, so that the combination hem remains dry and substantially unpressed until it has fully cleared the hemmer 35. The moisture which is applied by roll 36 does not travel rearwardly through the paper strip P into hemmer 35, because of the spacing between hemmer 35 and the rolls 3636a, and because the rate of feed is sufficiently rapid. The hem is thus formed in the dry or substantially dry condition.

I claim:

1. A method of forming a lateral and laterally U-shaped hem in a flat edge-portion of a necktie blank in a longitudinal hemming zone which has a longitudinal axis, which consists in feeding said blank forwardly in the direction of said longitudinal axis to the anterior end of said hemming zone, applying a flat supplemental and foldable strip to said fiat edge-portion at said anterior end of said hemming zone while said supplemental strip extends in the direction of said longitudinal axis through said hemming zone and through a feeding zone which succeeds said hemming zone, feeding said strip longitudinally forwardly in said feeding zone, feeding said edgeportion forwardly through said hemming zone by the frictional grip of said supplemental strip which is exerted in said hemming zone, forming a combination lateral and laterally U-shaped hem in said flat edge-portion and in said supplemental strip in said hemming zone by 8 laterally interfolding said edge-portion and said strip in said hemming zone, setting said combination hem, and then removing said supplemental strip from said combination hem.
